[Industrial applications]

 The present invention relates to a display device for a vehicle, and in particular, it is driven to rotate by an angle according to a measurement amount, and a pointer disc that emits a pointer pointer composed of a slit by the back light is arranged behind the pointer disc. And a range that overlaps with the movable range of the slit is translucent, and a dial that cooperates with the pointer disc to display the measured amount and a dial disposed on the back side of the dial to shield the light from the light source. And a light diffusing plate for diffusing and irradiating the back surface of the dial plate.

[0002]

[Prior Art]

 This type of conventional vehicle display device will be described with reference to FIGS. In the figure, 10 is a combination meter having a plurality of indicating instruments, for example, a speedometer for displaying a speed, a tachometer for displaying the number of revolutions of the engine, and the like. A pointer disk 12 disposed behind the dial disk 12, a character plate 13 arranged behind the pointer disk 12 for displaying the speed, the number of revolutions, etc. in cooperation with the pointer disk 12, and a back surface of the dial plate 13. Is disposed so as to cover the opening of the case body 11, diffuses light from a cold cathode tube 18 described later, and irradiates the light behind the pointer disc 12 and the dial plate 13. For example, a light diffusing plate 14 made of a white resin plate, a pointer shaft 15a fixed to the center of the pointer disk 12, and a meter internal unit 15 disposed behind the case 11 for rotating the pointer shaft 15a. , Accommodated in the case body 11, It has a reflector 16 having a columnar concave reflecting surface 16 a facing the opening side of the case body 11, and a cold cathode tube (discharge lamp) 17 as a light source arranged along a focal point f of the reflector 16.

As shown in FIG. 5, the pointer disc 12 has a black face 12a (hatched portion) formed on a disc-shaped transparent resin plate by a black printing process or the like. A slit 12b having a light-transmitting property is formed by not printing a part of the slit 12b toward the sheet, and the slit 12b serves as a pointer.

On the dial plate 13, a black face surface 13a (hatched portion) is formed on a transparent resin plate by black printing processing, and the scale and the number portion (scale portion) 13b are made into a translucent character. The scale portion 13b is formed in the range of approximately 8:00 to 4:00 clockwise in the clockwise direction of the dial of the timepiece. The portion that overlaps with the pointer disc 12 has a light-transmitting property and serves as a light-transmitting portion 13c. Further, as shown in FIG. 6, due to the eccentricity of the pointer disc 12 and the like, the black face surface 13a is extended by a minute range as an overlapping portion 131a so that the transparent portion 13c cannot be seen.

The light from the cold cathode fluorescent lamp 17 is diffused by the light diffusing plate 14, and the light heading for the reflector 16 is reflected by the reflecting surface 16 a as substantially parallel light, diffused by the light diffusing plate 14, and diffused by the light. Uniform and bright light is emitted behind the dial plate 13 and the pointer disc 12 through the plate 14, and only the scale portion 13b and the slit 12b are seen to emit light, and the pointer disc 12 is rotated by the meter internal unit 16. When it is moved, the emitting slit 12b rotates as a pointer to indicate the scale of the emitting scale portion 13b, and circular meter display is performed.

[Problems to be solved by the device]

In the above conventional vehicle display device, as shown in FIG. 6, a certain gap d ₁ is required between the pointer disc 12 and the dial plate 13 in order to smoothly rotate the pointer disc 12. Therefore, when the driver shifts his or her line of sight from the front position, the translucent portion 13c on the dial plate 13 for causing the slit 12b to emit light can be seen through this gap d ₁ and the appearance is poor.

In order to solve this, as shown in FIG. 7, it is conceivable to extend the overlapping portion 131 a of the black face surface 13 a to the range of the light transmitting portion 13 c where the driver can see through the gap d _1. However, the slit 12b has to be shortened by that amount, and as a result, the graduation portion 13b of the dial plate 13 and the tip of the slit 12b are separated from each other, and as shown in FIG. Will end up.

Further, since the slit 12b as a pointer is shortened, the entire indicating instrument can be seen as a small illusion, which reduces the commercialability.

Therefore, in view of the above-mentioned conventional problems, the present invention provides a good-looking vehicular display device in which unnecessary portions are not visible on the display surface with almost no deterioration in visibility, legibility, and merchantability. The purpose is to provide.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a vehicle display device made by the present invention is driven by an angle rotation according to a measurement amount, and a pointer disc, which is composed of a slit and emits light by the back light, and a pointer disc behind the pointer disc. The dial, which is transparent and has a range that overlaps the movable range of the scales, characters, and the slits, and which displays the measured amount in cooperation with the pointer disc, and is arranged on the back side of the dial. In the vehicle display device having a light diffusing plate that diffuses the light from the light source and irradiates it on the back surface of the dial, the wall that closes the gap between the pointer disc and the dial is the pointer circle. It is characterized in that it is erected on the dial along the outer circumference of the plate.

[0011]

[Action]

 With the above configuration, the wall that is erected on the dial plate prevents the range overlapping the movable range of the slits of the dial plate from being visible through the gap between the pointer disc and the dial plate.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In these figures, the same parts as those of the conventional one described above with reference to FIGS. 4 to 7 are designated by the same reference numerals, and detailed description thereof will be omitted.

In the drawing, along the outer circumference of the pointer disc 12, a thin plate-shaped member is formed on the dial plate 23 so that the transparent portion 23c cannot be seen through the gap d ₁ between the dial plate 23 and the pointer disc 12. The wall 21 is erected. The thinner the wall 21, the better.

Further, there is a gap d ₂ between the wall 21 and the pointer disc 12 for smoothly moving the pointer disc 12, and the character d is provided so that the transparent portion 23c cannot be seen from the gap d _2. The black face 23a of the plate 23 extends in the inside of the wall 21 as a small area, that is, an overlapping portion 231a.

With the above configuration, the wall 21 prevents the transparent portion 23c from being seen through the gap d ₁ between the pointer disc 12 and the dial plate 23, and the black face surface 23a serves as the overlapping portion 231a. It is possible to prevent the transparent portion 23c from being visible through the gap d ₂ between the wall 21 and the pointer disc 12 only by extending the minute range.

Therefore, it is not necessary to shorten the slit 12b, the distance between the graduation portion 23b and the tip of the slit 12b is hardly changed, that is, the visibility, readability and commercialability are not deteriorated. It is possible to prevent the light portion 23c from being visible. In addition, it looks good in terms of design.

The combination meter 10 described above can be preferably applied to a reflective display device for a vehicle as shown in FIG. In the figure, the combination meter 10 is installed in the handle column 33 so that the display surface 10a faces the reflection surface 32a of the reflection member 32 provided at the instrument panel position on the dashboard 31. . Then, the display image of the display surface 10a is reflected by the reflection surface 32a of the reflection member 32 toward the eyes of the driver so that the driver can visually recognize the vehicle information.

[0018]

[Effect of the device]

 As described above, in the vehicular display device according to the present invention, the range that overlaps with the movable range of the dial slit can be seen through the gap between the pointer disc and the dial due to the wall erected on the dial. Since the area that overlaps the movable range of the slit of the dial can not be seen with almost no shortening of the slit, visibility, readability and commercialability are hardly reduced, and unnecessary parts of the dial are not visible. You can
